Abstract

The invention concerns a joint connection with shaped sections (A, B, C, D, E, F) extending in three coordinate directions. The shaped sections (A, B, C, D, E, F) can be connected to each other simply and rapidly, using only a small number of parts, by virtue of the fact that a pair of parallel shaped sections (A, B, C, D, E, F) run a certain distance apart in each coordinate direction, the pairs of shaped sections having apertures which are aligned with the centre of the joint, are matched to the distance between the crossed pairs of shaped sections (A, B, C, D, E, F) and at least partly surround them, the shaped sections (A, B, C, D, E, F) being held together automatically.

Description

Node connection

The invention relates to a node connection with professional lab sections in three coordinate directions.

With such node connections, corner connectors are usually used. The corner connectors have receptacles in which the profile sections are inserted and fastened in them by means of clamping elements. A tool is usually used to actuate the clamping elements. The assembly and disassembly of the Prof i l abs c hn i 11 e is very time-consuming. This is particularly disadvantageous when setting up exhibition stands or similar complex areas. The production of the corner connector is expensive, since it must be ensured that the receptacles for the professional lab sections are exactly at a predetermined angle to one another.

It is an object of the invention to provide a node connection of the type mentioned at the outset which enables simple and quick connection of the profile sections and which requires only a small amount of work. The object of the invention is achieved in that a pair of parallel and spaced profile sections is provided in each coordinate direction, that the pairs of profile sections are provided with recesses which are aligned to the middle of the knot, are spaced from the intersecting pairs of profile sections and at least partially enclose them, and that the profile sections in the association are automatically held.

In the case of a pair of profile sections, the cutouts of one professional cut face the cutouts of the other professional cut. Thus, the four recesses of the two profi le sections form two images in which two further profi le sections are inserted. In the fully assembled knot connection, six professional sections are connected to each other and are held against each other only by means of the cutouts. This means that there is no need for a separate corner connector. This considerably reduces the costs of building a frame consisting of profile sections. Such a node connection can also be easily added in a short amount of time, since only the professional sections to be connected have to be placed next to one another. The professional lab sections are then firmly connected to one another. Clamping elements are no longer required. Furthermore, the knot formation according to the invention has an improved look, since no corner connectors and tensioning elements or screws are used between profile sections.

If it is provided according to an embodiment of the invention that the prof il abs c hn i 11 e are designed as a Hö l l r rof il abs c hn i 11 e and are made of elastic material, then the node connection can be designed so that the Prof il abs c hn i 11 e in the contact points deform elastically. This enables a high strength to be achieved in the knot connection. In addition, the professional lab sections are then held against each other without play.

The knot connection can then be variably formed in the longitudinal direction of the profile sections if it is provided that the profile sections in the longitudinal direction have a plurality of pairs of spaced recesses.

Because the professional sections 11 e are provided at their ends with connecting elements for connecting to further professional sections, the professional sections can be extended as desired.

A production variant for producing the profile sections 1111 provides that the pairs of cutouts are combined to form a common cutout. This is particularly advantageous if, for example, the profile section is designed as a sheet-like profi le. The recesses can then be punched out in one step.

If it is provided that panels are molded onto the profile sections, then partition walls, housings or the like can be built with the profile sections. In the areas of the node connection, the panels can be strung together without any gaps.

It is also possible that the professional lab sections are provided with longitudinal recordings. Plates can then be inserted into the recordings. Are the recordings on. the sides opposite the cutouts, so that the panels can be butted together without joints. Rails or the like can also be inserted into the receptacle, which can then be displaced in the longitudinal direction on the professional lab sections.

If it is provided that the professional sections of the same coordinate direction are connected to one another or that professional sections of different coordinate directions are connected to one another, then the number of individual parts to be handled is reduced, so that the assembly of the knot formation can be considerably simplified .

The invention is explained in more detail below with the aid of examples shown in the drawings for kneading inventions. Show it

Fig. 9 shows the connection of three professional lab sections standing at right angles to each other.

In Fig. 1 is a pre-assembled node connection from five tubular professional lab sections A, B; CD; E and the Profi labs chn i 11 F inserted into the knot, but not yet fully integrated. The Profi l section A, B; CD; E, F are provided with cutouts Aa, Aa1 to Fb1. Four cutouts Aa, Aa1 ... Fb1 are provided for each professional section A to F. The profile sections A, B are arranged parallel to each other. They run at a distance of My from one another. The recesses Aa, Aa 1 to Fb1 are arranged in pairs in the region of the ends of the profile sections 11a A to F. The recesses Aa, Aa 1 of the professional lab section A are arranged opposite one another to the recesses Ba, Ba1 in the region of the upper end of the professional section 11, A, B.

The recesses Ab and Bb are arranged at a distance KA and KB from the recesses Aa1 and Ba1. The recesses Ab, Ab1 of the professional section A are arranged in the recesses Bb, Bb1 of the professional section B in the area of the lower end of the professional sections A, B opposite one another.

The recess pairs Aa to Bb1 of the sections A, B form four pairs of recesses. The prof il abs c hn i 11 e C, D are inserted between the recesses Aa, Ba and Aa1, Ba1. The Prof il abs c hn i 11 e C, D in turn have recesses Ba, Ca1 and Da, Da1 in the area of the knot formation. The recesses of the Prof il abs c hn i 11 es C are opposite the recesses of the Profi lab section B. The profile sections C, D run parallel to one another and are arranged at a distance Mz from one another. The cutouts C, D encompass the cutouts vertically to the cutouts C, D, the cutouts E, F, the cutouts 11 e E, F with their cutouts Ea, Ea1, Fa, Fa 1 embrace the prof il abs c hn i 11 e A, B. The profile sections 11 e A, B are aligned vertically to the profile sections 11, E.

The node connection is set up in such a way that the profile sections A, B, C, D, E are connected to one another in the manner described above. The professional section F is then the last to be pressed into the knot connection. The profile section is made of a very elastic material, so that it elastically clamps the section sections A, B, C, D together.

In Fig. 2, the node connection of FIG. 1 is shown in exploded view. The professional salmon Ay, By der Prof il abs c hn i 11 e A, B are aligned so that they run parallel to each other on one level. The recesses Aa, Aa1, Ab, Ab1 of the Prof il abs c hn i 11 es A lie opposite the recesses Ba, Ba1, Bb, Bb1 of the Prof il absc hn i 11 es 1 at a distance My 1. The professional salmon Cz, Dz are aligned so that they are parallel to each other in a plane perpendicular to Professional level salmon Ay, By run. The recesses Da1, Da of the profile section D are opposite the cutouts Ca, Ca1 of the profile section C at a distance Mz1. In a further plane that is perpendicular to the planes formed by the professional salmon Ay, By and the professional salmon Cz, Dz, the professional salmon Ex, Fx of the profile sections E, F. The profile sections E, F lie opposite each other at a distance Mx1. If the distances My1, Mz 1, Mx 1 are reduced to the dimension shown in FIG. 1, a knot connection is obtained in which the individual professional sections AF mutually clasp each other. The center of the knot formation is then an intersection of the three levels of the six professional salmon Ay to Fx. 3 shows a node connection which is formed from six profile sections formed as polygonal profiles 11 to A to F. The professional cuts A to F are made of an elastic material, for example plastic chewing. This allows the sections A to F to be elastically clamped together in the knot connection.

4 shows a knot formation consisting of six profile sections formed as tubes. Connection elements Q, Q1 can be pushed into the front ends of the profile sections 11 to A to F. The connection elements Q, Q1 have two plug approaches and a paragraph. The diameter of the plug-in lugs is matched to the inner diameter tubes. The connectors can be pressed or glued into the pipes. The insertion movement of the connection elements Q, Q1 can be limited by means of the paragraph. A further professional section 11 can be pushed onto the free connector. To cover the front side of the professional section A, B to F, a plug R, R1 can be inserted into the front side of the

EN Profiles A to F are inserted. For this purpose, the plug R, R1 has a plug-in attachment which can be pushed into the front end of the profile section A to F. The plug R, R1 prevents the penetration of moisture into the professional section A to F or can be used as a foot plug on which the professional sections A to F are supported on the floor.

Between the two profile sections A, B there is a plate P on the profile section 11 C. The thickness of the plate P is matched to the distance between the profile sections 11 and A. The plate P can be used for example as a shelf or as a partition.

FIG. 5 shows various design variants of profile sections A. FIG. 5a shows a profile section made of solid plastic, which are cut out A, Aa, Aa1 notched into the Prof il abs c hn itt A. 5b, the cutouts Aa, Aa1 are combined to form a common cutout 4 Aa. If such profile sections A are combined to form a node connection, the interiors of the individual profile sections A of the node formation in the node center are connected to one another. This means, for example, that cables can be routed and protected in the interconnected profile sections. 5c shows a half-tube profile bent from sheet metal with corrugated sheet edges. The sheet metal edges are designed so that they have several cutouts Aa next to one another create lying. In the case of profi les cut A, the knot connection can be made at any point in the longitudinal direction of the profi section.

The sheet metal edges of the professional section spring back elastically in the knot connection so that the individual section sections are elastically clamped together in the knot connection. 6a shows a profile section A with recess Aa, Aa1. The profile section A has a slot on its side opposite the cutouts Aa, Aa1. Plates P are connected to the ends of the slot. for example, a dam material ffp la 11e or similar stabilizing elements can be inserted between the two plates P. Such a design of a profile section allows the construction of containers or partitions in a simple manner.

6b shows a profile section A with cutouts Aa, Aa1. On the side of the professional lab section A opposite the recesses Aa, Aa1 there is a receptacle ASP running in a longitudinal axis. For example, plates P can be inserted into the receptacle ASP. But it is also conceivable to insert square profiles S in the groove. If the V i e rkantp rof i l e S protrudes above the profile, then the ASP mount protrudes, the square profile S can be used, for example, as a spring element on which a plate P with a side recess can be placed.

7, 8 and 9 show the connection of several profile sections 11a A, B, C to one another. Fig. 7 shows the connection of two parallel to each other Prof abs abs cni 11 e A, B. The Prof il ab schnn 11 11 A A, B are at one of their ends ends by means of a s abs chni ttes connected. The recess Aa1 of the professional lab section A is opposite the recess Ba 1 of the professional section B -. The recess Aa of the professional lab section A is opposite the recess Ba of the professional lab section in the area of the connecting piece. Using three system elements of the type shown in FIG. 7, a knot connection can be produced with little assembly effort. The free ends of the sections A, B have connection openings AQ on the end. The connection openings serve for receiving connections elements Q, Q1, as are shown for example in FIG. 4. This means that additional professional sections A, B can be connected. If no further sections are to be connected, the connection openings AQ, BQ can be closed with plugs R, R1 shown in FIG. 4. The U-shaped system element shown in FIG. 7 can, for example, be produced from a sheet metal.

In Fig. 8, a T-shaped system element with two professional lab sections A, B is shown. The two professional sections A, B are firmly connected. The profile sections 11 A, B are designed as full profiles, whereby the material has elastic properties. Connection openings AQ, BQ are made in the front sides of the profile sections 11e A, B. The connection openings AQ, BQ serve only to connect further Prof il abs cni 11 e. In . the sections A, B have the recesses Aa1 and Ba, Ba1. A node connection can be established by means of three system elements of the type shown in FIG. 8. 9 shows a system element consisting of three profile sections 11, A, B, C, the profile sections 11, A, B, C are at right angles to one another. Connection openings AQ, BQ, CQ for connecting further profile sections are made in the ends of the profile sections A, B, C. Recesses Aa1, Ba1, Ca1 are made in the profiles 11a A, B, C sinσ for connecting a system element of the same type. Individual profile sections A to F can also be used optionally for establishing a node connection with the system elements shown in FIGS. 7, 8 and 9.
